Abstract

The punching tool has a U-shaped bracket, one arm of which has a guide for the punch reciprocating to and from a cutter plate on the other arm. Springs between punch and guide thrust it away from the plate to allow insertion of a plate be machined. When force is applied to the punch, the guide is first pressed against the plate to be machine and the punch is then actuated. The guide for the punch (17) is formed by a component fixed to the bracket arm (2), this arm being sufficiently flexible for the component first to be pressed against the plate (21) to be machined, and which is pressed against the cutter plate before the punch operates.
